FFmpeg Installation on the Jetson TX2

While Nvidia does not officially support FFmpeg on Jetson devices (Nano, TX2), it’s worth noting that FFmpeg can leverage Jetson’s powerful hardware resources as an encoder and decoder. This unique capability makes it a compelling choice for your projects. Here’s a detailed guide to installing FFmpeg on the Jetson TX2 using JetPack SDK 4.3.

Prerequisites

Since FFmpeg is built from source, we first need to install the necessary dependencies:

$ sudo apt build-dep ffmpeg

If you encounter the error E: You must put some ‘source’ URIs in your sources.list, uncomment the source lines in /etc/apt/sources.list and update the package lists:

$ sudo vi /etc/apt/sources.list

Uncomment the line starting with deb-src, save (:wq), and then update the repository:

$ sudo apt update
$ sudo apt build-dep ffmpeg

Build dependent libraries

Clone the Jetson-optimized FFmpeg repository and build it:

$ git clone https://github.com/jocover/jetson-ffmpeg.git
$ cd jetson-ffmpeg
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
$ sudo ldconfig

FFmpeg patch and build

Clone FFmpeg repository and apply necessary patches:

$ git clone git://source.ffmpeg.org/ffmpeg.git -b release/4.2 --depth=1
$ cd ffmpeg
$ wget https://github.com/jocover/jetson-ffmpeg/raw/master/ffmpeg_nvmpi.patch
$ git apply ffmpeg_nvmpi.patch
$ ./configure --enable-nvmpi
$ make -j4 2>&1 | tee make.log
$ sudo make install

Confirm installation:

$ which ffmpeg
/usr/local/bin/ffmpeg
$ ffmpeg -codecs | grep 264

You should see the output confirming that h264_nvmpi is included in the H.264 decoder and encoder.

Once you’ve followed these steps, you can confirm the successful installation by checking if h264_nvmpi is included in both the H.264 decoder and encoder. This confirmation will give you the satisfaction of a job well done.
